Longline Corset with Adjustable Shoulder Straps | Private Label Manufacturer & Wholesale OEM/ODM

The Longline Corset with Adjustable Shoulder Straps provides extended torso coverage and structural support. Engineered for apparel brand owners, shapewear distributors, and private label collections, this model combines traditional boned shaping with the ergonomic load distribution of adjustable straps.

Our manufacturing facility utilizes automated pattern cutting and reinforced multi-needle stitching to maintain dimensional stability across bulk orders. Designed for integration into retail shapewear or fashion lines, each unit undergoes strict quality auditing to meet international retail standards.

Key Features

01/

Extended Torso Architecture: Extra length targets the mid-to-lower abdomen and hips, smoothing transition lines under apparel.

02/

Adjustable Load-Bearing Straps: Width-graded straps reduce shoulder dig-in and allow vertical tension adjustment.

03/

Rigid Structural Boning: Alternating steel and flexible spiral boning prevents roll-down while accommodating torso articulation.

04/

Reinforced Closure System: Heavy-duty front metal busk paired with industrial-strength back lacing grommets.

05/

Anti-Chafing Interior Lining: Breathable cotton-blend inner facing minimizes friction during extended wear.

Materials & Construction

Shell & Lining Selection: Outer layers utilize high-density woven fabrics resistant to snagging and seam slippage. Inner linings use combed cotton treated with eco-friendly finishing agents to prevent skin irritation.

Boning Encasing: Each steel bone is encased in heavy-gauge cotton tape and double-stitched using nylon core-spun thread to eliminate bone poke-through.

Grommet Setting: Back lacing eyelets are brass-based with nickel plating, pressure-set via pneumatic presses to prevent pull-out under maximum lace tension.

Stitch Density: Main structural seams maintain 10–12 stitches per inch (SPI) to ensure seam integrity under high lateral stress.

Sizes & Customization

Size Grading: Standard international sizing charts (US, EU, UK) available. Custom grading based on client-provided tech packs accepted.

Hardware Options: Custom logo laser-engraving on metal busks, branded zipper pulls, and customized metal eyelet finishes (matte black, gold, silver, bronze).

Labeling Services: Woven main labels, care label placement, heat-transfer size tags, and custom barcode hangtags applied per unit.

Applications

Quality Control

Manufacturing follows a 4-stage inspection protocol:

Raw Material Inspection	Fabric tensile testing, colorfastness evaluation (ISO 105-C06), and hardware corrosion resistance checks.
In-Line Inspection	Monitoring stitch tension, bone alignment, and symmetry during assembly across 50+ sewing stations.
Finished Product Audit	100% manual check for loose threads, busk alignment, and strap load-bearing stability.
AQL 2.5 Standard	Final random sampling inspection conducted prior to carton sealing.

Packaging & Private Label OEM/ODM

Packaging: Individual flat-pack sealing in recyclable low-density polyethylene (LDPE) polybags with desiccant. Master cartons use 5-layer corrugated cardboard rated for international transit.

OEM/ODM Execution: Rapid sample turnaround (7–10 business days) based on tech packs or physical samples. Bulk lead times range from 25 to 35 days depending on order volume and fabric availability.

Frequently Asked Questions

Q: What is the Minimum Order Quantity (MOQ) for private label orders?

A: The MOQ is 300 pieces per colorway using standard in-house fabric inventories. For custom-dyed Pantone shades, the MOQ is 1,000 pieces per color.

Q: Can we substitute spiral steel bones with plastic boning to reduce cost?

A: Yes. Plastic or lightweight memory boning can be substituted upon request, though structural rigidity and recoil memory will decrease.

Q: What testing standards do your wholesale and OEM fabrics meet?

A: Materials comply with OEKO-TEX Standard 100 for harmful substances, REACH regulations for the EU market, and CPSIA requirements for the US market.

Q: How are custom logo metal busks manufactured?

A: Logos are laser-etched onto the stainless steel busk plates prior to final protective coating application, ensuring permanent branding resistance to sweat and friction.

Q: What is the typical lead time for pre-production samples?

A: Standard physical sample creation requires 7 to 10 business days after tech pack sign-off and material confirmation.

Q: Do you provide drop-shipping services for bulk orders?

A: We operate primarily on FOB, CIF, or DDP wholesale terms, shipping directly to central warehouses or designated fulfillment centers rather than individual drop-shipping.
